Abstract

弹子门锁防撬装置分别固定于门和门框上锁的 前面处。安装时先在门侧凿一劈槽,劈槽的前部固定 一块永久磁铁,劈槽底部并且紧靠锁体处固定防撬挡 片。在门框锁舌壳的前面固定可沿纵轴转动的防撬 舌片。关门时,防撬舌片受磁铁吸引插入防撬挡片 内、外来的拨片,撬物进入时被导引到挡片上,开门 时,舌片被门推贴到门框上。

Description

本实用新型涉及与锁有关的附件。
在已知技术中,锁的防撬、防拨方案众多。经检索得知,中国专利公报中公开的有关方案可分为两大类。一类是在锁本身上进行开发:以89220397.8号申请为代表,让锁体略突出门缘,锁舌壳相应缩入门框,从而使锁体、锁舌壳的配合面离开门与门框的配合面。90201401.6号申请则在上述基础上,在锁体突出门缘的那部分上增设一条防撬齿扣;以90105008.3、90213112.5、90201317.3等号申请为代表,在锁舌斜面或前面上纵向开置防撬槽。另一类则是为数极少的加固部件,其功能在于防踢。总之,附加的防撬装置尚未产生。
本实用新型的任务是提供一种弹子门锁的防撬装置。
任务是这样完成的(站在门内,面朝室外并且锁舌壳位于右门框条上作为以下描述的朝向):在锁体前方的门右侧面上凿一劈槽,劈尖离门的前面有一小段距离。劈槽前部固定一块永久磁铁。劈槽的底部,也就是紧靠锁体处固定有防撬挡片。在门框上锁舌壳的前方固定一可绕纵轴转动的防撬舌片,当门关闭时,防撬舌片受磁铁吸引,转向并且插入防撬挡片的左侧。来自门外的拨片、撬片被防撬舌片导引到防撬挡片,避免了与锁舌斜面的接触。开门时,防撬舌片被门推向门框。
总之,所说的弹子门锁防撬装置,至少由固定于门侧锁体前面的劈槽前部的永久磁铁、固定于劈槽底部紧靠锁体处的防撬挡片以及固定于门框上锁舌壳前方并且可沿纵轴转动的防撬舌片组成。
按本方案制造、安装的防撬装置,主要优点在于提高了弹子门锁的防撬性能,而且只要在现有门锁上加装而已,比较方便。
附图为本实用新型实施例之一的使用状态的横截面示意图。
下面结合附图,描述实施例。
在门的侧面上锁体的前面处凿一劈槽[2],劈槽[2]尖部与门的前面有一小段距离,劈槽[2]的底部紧靠锁体[4]。在劈槽[2]前部固定永久磁铁[1]。在劈槽[2]的底部紧靠锁体[4]处固定防撬挡片[3]。如果把防撬挡片[3]制有折角,则可减少该片厚度。可绕纵轴转动的防撬舌片[5]固定于门框上锁舌壳[6]的前面。防撬舌片[5]可以制成合页形式,也可以与锁舌壳[6]制成一体。所说的合页形式,也包括合页中的一页为防撬舌片[5],另一页为复盖锁舌壳[6]的面(留出锁舌孔);或者为部分盖住锁舌壳[6]并钩住锁舌孔前长边的面。
为了保证门与门框的紧密配合,还可以在锁的上方或下方,或上下两方安装防撬扣。安装在门上的防撬扣,在门关闭时扣入装于门框上相应处的防撬扣挡上,使门缝难以扩大。
